Title : Respiration (CO2 flux) from urban and pen-urban soils amended with green waste compost
Journal : Geoderma
Comment : The mean and range of soil respiration rates were significantly increased by compost incorporation both in the field and in the laboratory (≤1.5 and ≤3.5 μmol CO2m2 s-1 respectively), due to increased substrate availability via compost. However the sensitivity of CO2 flux to temperature changes was both reduced and stabilised after compost additions (Q10 ~ 1.1), compared to the control without compost (Q10 ~ 2). In this respect urban soil management using green waste compost could reduce the susceptibility of soils to C losses over longer terms whilst providing other soil quality benefits in the short to medium terms.
